Sorry if I am asking a question that is a common one, but I have searched
through both Papajohn.org and googled on this without finding any solution
to my problem:

The sound on my projects goes missing when saving the movie to the
computer...

I have sound in the preview, the sound get transferred to my computer and
everything looks and sounds OK until I play the finished file.

This usually happens after me inserting text onto a clip, but the sound
might also disappear without me finding any reason.

I usually save the file using the 2.1 local playback setting, but this
happens using other settings too.

Any tips for this?
